Abstract 
First we synthesized five sulfanilamide derivatives. Then the azo dye was synthesized by the coupling of diazoniumsalt of sulfanilamide derivatives with 8 hydroxy quinoline  ligand. So D1-D5 Chelating azo dyes were prepared.After syntheses compounds were characterized by chemical as well as instrumental methods. like Melting point, elemental analysis, UV–visible spectroscopy and IR spectral studies.
Key words: sulfanilamide derivatives , 8-hydroxy quinoline  Azo dye, UV-visible and IR   Spectroscopy.
